HALFEN Natural stone façades – many advantages from one source
Introduction
Natural stone has numerous advan-tages when used for designing façades. It is a durable, low maintenance material which improves a building’s sound insulation. Natural stone façades also contribute to the aesthetic appear-ance of your project and makes it "standout".
Its heat storage properties make it an excellent material for insulating against summer heat. The heat is kept away from the core of the building, reducing the necessity to cool the building. These are just a few of the many advantages of designing façades with natural stone.
Natural stone façades are usually designed and constructed as ventilated curtain façades. HALFEN Natural stone fixing systems are the optimal solution for realising this type of ventilated curtain façade.

Quality assurance and safety are of ever increasing importance in the construction of buildings. The HALFEN Body anchors and HALFEN Grout-in anchors have been quality tested and certified by the Nuremberg LGA Landes gewerbeanstalt (Nuremberg based independent certification agency). The LGA is part of the “TÜV Rheinland Group”, Germany’s renowned, inde-
pendent and neutral, safety and quality testing organisation. The quality cer-tificate is the first independent quality certificate awarded for the production and the construction of façade systems of this type.
The precondition for a quality-seal award are comprehensive tests by the LGA. This includes assessment of the manufacturing process, the static load
capacities, and the complete documen-tation of the load-bearing anchors. It is a comprehensive and independent quality assurance covering all characteristics of the product.

Thermal bridges with HALFEN Natural stone support systems
Introduction
Technical Support
HALFEN Engineering SupportHALFEN engineering can provide planning and design service plus complementary consultation for your individual projects. Please contact us: see page 28 for contact information. Alternatively, simply scan the QR Code to visit our mobile website.
To meet the requirements for calculat-ing thermal bridges, HALFEN provides the thermal bridge coefficient for their body anchors, HALFEN SUK Sub-structures elements and grout-in anchors.
The -value defines the effect of a three-dimensional point thermal bridge caused by the fixing of the anchor and penetration of the thermal insulation.Using these values the planner can exactly calculate the effect on the ther-mal transfer coefficients U [W/m²×K]
of the building caused by the HALFEN Natural stone support system.The values are dependent on both the thickness and thermal conductivity of the insulation, and the material of the main structure (concrete/brickwork).

Dynamic loads with HALFEN Natural stone support systems
Introduction
HALFEN Natural stone support systems can also be installed in seismic active regions.
Grout-in anchors UMA/UHA are statically designed for seismic loads and can fully transfer the vertical loads on pages 13 and 15 in all three load directions. With appropriate design all HALFEN Natural stone anchors can be adapted to meet safety requirements for the relevant earthquake zones.
SeismicSeismic load
Channel support systems are the optimal solution for reducing thermal bridges. HALFEN SUK and UKB are anchored to the building at only a few fixing points. All elements anchored to the load-bearing structure are manu-factured from stainless steel.
Stainless steel has a fourteen times lower thermal conductivity than aluminium. The higher strength of stainless steel compared to aluminium also makes it possible to design ele-ments with a smaller cross-section.
This has a positive effect on heat trans-mission through the anchor element. It is also possible to place a thermal separator between the anchor and the load-bearing structure. This feature reduces thermal bridging and therefore heat loss.

Introduction
The unique design of natural stone façades demands special solutions for anchoring. The following are examples of custom solutions developed byHALFEN for natural stone façades.
Custom solutions
An important design feature in this façade are the 90 degrees projecting natural stone strips. These strips are attached to the precast sub structure of the building using HALFEN Natural stone anchors.

FeaturesHALFEN Body anchors used together with HALFEN HTA/HZA Cast-in chan-nels guarantee maximum adjustability to compensate for on-site tolerances.
HALFEN Body anchors can also be fixed to a suitable load-bearing structure using HALFEN Anchor bolt systems. HALFEN Body anchors cover a wide range of applications for fixing natural stone.
FeaturesHALFEN Grout-in anchors are a tra-ditional method of anchoring natural stone façades. The tubular section of the UMA / UHA anchors makes them suitable for both horizontal and vertical joints in natural stone panel façades.
Adjustment is by casting the anchorsin a sufficiently large, pre-drilled mortar filled hole.
The joints between the natural stone slabs must be supported with shims until the mortar has hardened and final load-bearing capacity has been reached.
Advantages
• type tested
• one type of anchor for both horizontal and vertical joint fixing
• TÜV / LGA tested quality
• anchored in the drillhole using cement based mortar
• can be used for large stand-off installations and high loads

HALFEN SUK Stainless steel support structure
HALFEN UKB Support structure in stainless steel and aluminium
Applications
FeaturesThe HALFEN SUK Stainless steelsupport system is ideal both for new building and modernization projects. Its unique characteristic is the capacity to span a non-load-bearing substrate.
It can be used for installation of large, varying stand-off distances from the load-bearing structure. A4/AISI 316 grade stainless steel material guarantees a high resistance against corrosion.
Fewer required fixing points reduce installation costs for the whole support system. Fewer fixing points also reduce heat-loss, resulting in very good thermal properties when using the SUK System.
Advantages• height of suspended channel system
freely adjustable
• horizontal adjustment (using a spade bolt)
• fast assembly and therefore faster construction times
• proven in numerous projects
• spans non-load-bearing sub structures

HALFEN Body Anchors
HALFEN DH Body anchor
HALFEN DH Body anchors are 3-dimensionally adjustable. They are designed to carry only horizontal tension or pressure loads. DH Body anchors are used in combination with HALFEN BA and DT Body anchors.
The anchor is mainly used at slab edges and corners or for parapet elements.It is designed for stand-off installation of 60 to 320 mm and horizontal loads of up to 1,300 N. The stand-off distance from the main load-bearing structure is adjusted using the spade bolt.
Vertical adjustment is with the 9 × 30 mm slot. This anchor is also laterally adjustable by swivelling the whole unit. The body anchor is delivered with an additional counter nut, which addition-ally locks the spade bolt.

HALFEN UHA Restraint anchor
HALFEN Grout-in Anchors
The round cross section of the HALFEN UMA Grout-in anchor makes it especially suitable for grouting in brickwork (> M12/IIa) and in concrete (> C12/15). The anchor has the same load-bearing capacity in horizontal and vertical joints. Depending on the anchor type, stand-off installations of up to 300 mm with maximum vertical loads of 4300 N are possible. A sufficiently dimensioned drill hole, filled with cement mortar, allows three-dimensional adjustability of the anchor. The anchors are type tested and are available in vari-ous designs.
Separate serviceability certificates for anchor bending are required.
Available UMA designs:
HALFEN UHA Restraint anchors are used to support horizontal compression and tension forces. The UHA Restraint anchor is used in combination with UMA Grout-in anchors. Restraint anchors are used

Advantages of the HALFEN Support structure systems
HALFEN Support Structure Systems
The standard HALFEN Support structure system consists of a series of vertical channels between floors. Fixings are only required at compara-tively large intervals. This reduces the number of required connections to the underlying main support structure.
The Advantages• the building’s weatherproofing and
insulation is penetrated less• the number of thermal bridges is
reduced. This helps to observe the applicable energy-saving regulations. In Germany: EnEV = German Energy-Saving Regulations
HALFEN Support structures are also suitable for spanning non-load-bearing constructions.
Furthermore, using pre-install support construction systems permit fast and economical fixing of façade panels and slabs.
Two main categories of support structures for different requirements are available from HALFEN:
• HALFEN SUK Stainless steel support structures
• HALFEN UKB Aluminium support structures
The HALFEN SUK stainless steel support structure is suitable for durable constructions in harsh environments and for high loads.The HALFEN UKB System channel support structure is very easy to install and a cost effective alternative.

HALFEN SUK Stainless Steel Support Structure
The HALFEN SUK System is an adjust-able suspended channel system with support and restraint anchors that can easily be adjusted to any height for façade stand-off installations > 160 mm.
It is ideal for new constructions and remodelling projects. The system is especially suited for natural stone façades with large and varying distances to the load-bearing wall.
The system is made up of a small number of easy to install components and is therefore increases ease of instal-lation. Non-load-bearing areas and recesses can be spanned.

HALFEN UKB Aluminium Support Structure
The HALFEN UKB System is a freely adjustable aluminium and stainless steel support structure with vertical U-profiled support elements for use in the ventilation gap of natural stone façades. This type of construction reduces thermal bridges to a minimum.
The type 606 HALFEN BA Body anchors are fixed to the front of the vertical channels.The UKB Support structure allows for stand-off installation between 130 and 320 mm and three-dimensional adjustments of ± 20 mm.
The support brackets are made of stainless steel A4.They are either fastened to HALFEN Cast-in channels or to the load-bearing main structure using HALFEN Anchor bolts. Depending on environmental conditions, protection against surface corrosion must be taken into account, for example with barrier tape.

The soffit / jamb brackets and restraint angles significantly improve the connec-tion between façade and soffit / jamb elements, especially when using natural stone.
The non DIN compliant pin and glue process can be omitted. The façade slabs can be installed quickly, simply and efficiently in the precast factory or on site.
The support anchors are adjustable (up to ±5 mm); façade, soffit and jamb panels can also be installed with open joints. To prevent stresses the panels are fixed with support brackets and restraint anchors.

Scaffolding used in the construction industry must be planned in accord-ance with DIN EN 12810 and DIN EN 12811. These standards include type specific requirements for initial scaf-folding for building and also for façade installations and maintenance work.To connect to the supporting structure of the buildings, scaffolding anchors are used which must be technically capable of securing the scaffolding reliably through the thickness of the façade. This is the only safe method to install the insulation and façade elements for the building from the scaffolding.The position, fixing method and load-bearing capacity of the scaffold anchors must be taken into account when planning the façade and included in the building’s documentation. The choice of anchors depends on the type of scaffolding selected, the anchor grid
of the scaffolding and the distribution of the joints in the façade. We manufacture the scaffold anchors and also specify the maximum working loads for each anchor both vertically and horizontally to the façade to ensure the required reliability in planning and application.
Loads from the scaffold are transferred to the HALFEN Scaffold anchors using reusable straps or ringbolts. HALFEN Scaffold anchors remain in the building after dismantling the scaffold and are concealed so not to disrupt the façade appearance. This ensures that a scaf-fold can be re-erected later without
additional anchoring measures.To meet the ever-increasing demands on thermal insulation HALFEN HGA-F Scaffold anchors can be installed with a thermal separation strip between the building and the anchor. The thermal separation strips reduce the heat loss caused by the scaffold anchors and im-proves the heat transmission efficiency of the building.

Ins ta l la t ion Sequence
Anchoring in horizontal joints
Note:Natural stone slabs are
generally fixed at four points. Thermal insulation should be cut out before drilling the fixing holes.
Support anchors
Installation direction:from left → right orfrom right → leftalways from bottom → top
▸ Ensure the façade is measured correctly and tolerances have been considered.
▸ Erect any required scaffolding.
▸ Cut and remove a section of the thermal insulation to drill the hole for the anchor bolt. The insulation is replaced after anchor installation.
▸ Drill the dowel holes for the first and second row of slabs, ensure correct hole diameter and minimum drill hole depth.
▸ Remove all dust from the hole.
▸ Fix and align the lower row of body anchors (support anchors) with approved anchor bolts i.e. HALFEN HB-BZ.
Note: Always use the supplied washer when using HALFEN Bolts or HALFEN Dowels to attach the HALFEN DH Body anchor to
the main load bearing structure.
▸ Replace the previously removed thermal insulation.
▸ Fill the pin holes above the anchor with mortar.
▸ Place the first row of slabs onto the support anchors.
▸ Fix and align the support anchors for the second row of slabs with approved anchor bolts i.e. HALFEN HB-BZ.
▸ Make any fine adjustments to the first row of slabs: allow at least a 2 mm gap between the top edge of the lower row of façade slabs and the bottom edge of the arm of the support anchor for the second slab row (see detail).
▸ Push the anchor pin through the hole in the spade bolt and into the sleeve in the slab below.
▸ Dimensions acc. to the detail “Pin, fixing hole and joint dimensions [mm]” (see right) must be observed!
▸ The second row of slabs is then installed and the procedure repeated.

Construction details from DIN 18 516, section 3
Anchor pinsThe anchor pins extend into the holes drilled for the pins in the edges of the slabs. The holes are approximately 3 mm larger than the diameter of the pins.
Anchor materialAnchors and pins must be of stainless steel corrosion resistant class III mate-rial, according to EN 1993-1-4: 2015. For detailed steel material specifica-tions see page 2.
Edge distancesThe standard distance from the corner of the panel to the centre of the hole is 50 mm.
The planning of natural stone anchor fixings is based on the details shown in figures a) to e). This allows fast and accurate installation to ensure cost effective fixing of natural stone panels.
Panel weight:FV = b [m] × h [m] × d [m] × g [kN/m3]
Design Fundamentals
b) Dimensions of natural stone
width b
height h
thickness d
Calculating the panel weight:
The thickness of the panel from the hole to the panel face must not be less than 10 mm (see section A-A on page 24). Minimal thickness of panel ≥ 30 mm.
Concrete anchoring substrateWhere the load-bearing structures are heavily reinforced and highly stressed, for example reinforced concrete columns or lintels, the type and location of the anchors should be specified in cooperation with the structural engineer. Anchors connected to HALFEN Cast-in channels must be installed in accord-ance with the approval for HALFEN HTA Channels.
